Find the value of x and y in the rhombus.

Inga [223]

Answer:

x = 10, y = 13

Step-by-step explanation:

Because EYD is 70, then FEY is also 70. Both triangles are identical.

This means:

45 + 70 + 7x - 5 = 180

7x = 70

x = 10

EFY and EDY are identical and this means:

7x - 5 = 5y

7*10 - 5 = 5y

5y = 65

y = 13

10. Polygon WXYZ has vertices W(-1.5, 1.5),

vovikov84 [41]

Answer:

See explanation

Step-by-step explanation:

Polygon WXYZ has vertices W(-1.5, 1.5), X(6, 1.5), Y(6, -4.5), and Z(-1.5, -4.5).

Find the slopes of all sides:

$WX:\ \dfrac{1.5-1.5}{6-(-1.5)}=\dfrac{0}{7.5}=0$ - horizontal line

$XY:\ \dfrac{-4.5-1.5}{6-6}=\dfrac{-6}{0}$ - slope undefined, so the line is vertical

$YZ:\ \dfrac{-4.5-(-4.5)}{-1.5-6}=\dfrac{0}{-7.5}=0$ - horizontal line

$ZW:\ \dfrac{1.5-(-4.5)}{-1.5-(-1.5)}=\dfrac{6}{0}$ - slope undefined, so the line is vertical

Vertical and horizontal lines are perpendicular, so all angles W, X, Y and Z are right angles. Hence, quadrilateral WXYZ is a rectangle

When the store had sold 2/9 of the boots that were on display, they brought out another 34 pairs from the stock room. If that ga

nikdorinn [45]

Let us assume number of boots pairs were on display originally = x.

We are given 2/9 of the total boots pairs we sold.

So, 2/9 of x boots pairs were sold, that is

Number of boots pairs were sold = 2/3 x.

Number of boots pairs brought out from store = 34.

Remaining pairs of boots = 174 pairs.

So, we can setup an equation,

Total number of boots pairs - First number of boots pairs sold + number of boots pairs brought out from store = Remaining pairs.

x - 2/9 x +34 = 174.

Subtracting 34 on both sides, we get

x - 2/9 x = 34-34 = 174-34

x- 2/9 x = 140 .

Simplifying left fracions by taking common denominator,

9/9 x- 2/9 x = 140

(9x-2x)/9 = 140.

7/9 x = 140.

Multiplying both sides by 9.

9* 7/9 x = 9*140.

7x = 1260.

Dividing both sides by 7.

7x/7 = 1260/7

x= 180.

Therefore, 180 pairs were on displayed originally.

Answer:

so for the first one the equation is y=5x+30 but then u gotta plug 3 in for x becuase x is the supposed number of hours thhat e is working and so for your tabule jst put 1,2,3,4,5 for the x spot and tghe write the euation in hte blank row and then put the answer for pulging it in with the differnt numbers for y
